Henry<sup>®</sup> Moisture retention/drainage (DB50/100 and DBR50/100)

Moisture retention/drainage (DB50/100 and DBR50/100)

DB50/100 Root Bloc root barrier system consists of a high-strength, dimpled polymeric sheet. The perforated core has two specific fabrics attached to the top and bottom core layers.

The top fabric contains a root barrier embodied into the non-woven fabric designed to stop root penetration and promote secondary root branching. The bottom fabric layer provides excellent cushioning properties, delivering extra protection to the roofing membrane.

Typically, DB100 Rootbloc is used for intensive applications (larger plants/trees with aggressive root systems), while DB50 is used for extensive applications (grasses/small non-aggressive root systems).

Additionally, Henry® offers DBR50/100, an option that has a chemical root barrier.

Features

  • High compressive strength
  • Root barrier, strategically located at soil level, prevents root damage to insulation and drainage layer
  • Reduces storm water runoff to drains
  • Provides excellent water storage capacity and aeration for the growing medium
